ID:170111 Error on line <number> of Routing Constraints File. Cannot use route port <name> with atom "<name>" due to atom's current configuration

CAUSE: An error occurred on the specified line number in the Routing Constraints File (.rcf). You tried to use the specified route port with the specified atom. However, the Quartus Prime software cannot use the specified route port with the specified atom due to the atom's current configuration. The Fitter ignored the route port assignment and will attempt to route the connection using another port.

ACTION: If you want precise control of the specified route port, change the specified atom's configuration, or choose a different route port. If you want to keep the specified atom's current configuration, remove the route port assignment to allow the Fitter to choose a legal route port.
